ADJUSTABLE SHADE-ROLLER BRACKET.

Specification of Letters Patent.

Patented Feb. 6, 1912.

Application filed December 10, 1910. Serial No. 596,647.

To all whom it may concern Be it known that I, CHARLES MASON, citizen ofthe United States, residing at Boston, in the county of Suffolk andState of Massachusetts, have invented certain new and usefulImprovements in -Adjustable Shade-Roller Brackets, of which thefollowing is a specification.

This invention relates to supportlng brackets for shade rollers and hasfor its object the provision of a comparatively simple and thoroughlyeflicient device of this character, the construction of which is suchthat the bracket may be readily attached to a window frame without theemployment of screws, nails and similar fastening devices.

A further object of the invention is to provide a bracket, capable ofbeing adjusted vertically of a window frame and which will admit of theshade roller being reversed without the necessity of reversing saidbracket.

A further object is to provide a bracket, the shade roller of which maybe fitted thereto without the employment of a chair, step ladder or thelike for the operator to stand on when hanging the shade roller.

A further object is to provide a supporting bracket including pivotallyunited members adapted to frictionally engage the walls of the sashreceiving channel or run, the construction of the bracket being suchthat it may be adjusted vertically of the window frame withoutinterfering with the sash cord or pulley.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andefficiency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

For a full understanding of the invention and the merits thereof,reference is to be had to the following description and accompanyingdrawings, in which:

Figure 1 is a transverse sectional view of a portion of a windowprovided with a shade supporting bracket constructed in accordance withmy invention; Fig. 2 is a detail perspective view of a portion of oneside of taching the bracket thereto Fig. 3 is a top plan view, partly insection, of one of the roller supporting brackets detached; Fig. 4 is arear elevation of the bracket.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The improved supporting bracket form ing the subject matter of thepresent invention is principally designed for attachment to windowframes and similar closures and by way of illustration is shown inconnec tion with a window of the ordinary construction, in which 5designates the frame having guiding channels or runs 6 formed thereinfor the reception of the sashes 7, the latter being provided with theusual sash cords 8 extending over pulleys 9 for connection to the sashweights.

The device comprises co-acting members 10 and 11, each preferably formedof a single piece of fiat metal having its opposite longitudinal edgesconcaved at 12, said members having their central portions intersectingand pivotally united at 13. the metal forming the opposite ends of themembers 10 and 11 being bent laterally to form angularly disposedflanges 14- adapted to bear against and positively engage the walls ofthe adjacent run or channel 6, thus to hold said bracket in position onthe window frame. The members 10 and 11 are also formed withsubstantially rectangular openings 15 adapted to receive the pins ortrunnions of the shade roller, indicated at 16, there being preferablyfour of such openings formed in each bracket, as shown. The metalforming the flanges 14 is bent laterally to produce substantiallyhorizontally disposed lips 17, the free edges of which are toothed orserrated so as to bite into the walls of the run or channel 6 and thusassist in holding the bracket in adjusted position.

The metal forming the lower ends of the members 10 and 11 is cut orsevered and rolled upon itself to produce depending finger pieces 18 bymeans of which said members may be drawn together so as to permit thebracket to be readily inserted within the run or channel. 6. Spaced fromthe inner face of the member 10 and secured in position on the bracketby the pin 13, is a disk 19, between which and the bracket is a windowframe, showing the manner of at- I interposed a coil spring 20. Theopposite ends of the wire forming the spring 20, are extended ondiverging lines, while the free ends of the wire are bent to formterminal angularly disposed fingers 21 adapted to enter suitable openins 22 formed in the members 10 and 11, some of said openings being formedin the flanges 14, as shown. The tension of the spring 20 is such as toforcethe upper ends of the members 10 and 11 apart so that when thebracket is inserted in the run or channel 6, the spring will force themembers laterally or apart so that the teeth 17 thereof will bite intothe walls of the channel. Thusit will be'seen that by grasping thefinger pieces 18 and forcing the latter together, the bracket may be adjusted vertically of the window frame, the

. spring serving to force the members 10 and 11 apart and thus securethe bracket in different positions of adjustment. It will also be notedthat the construction of the bracket is such that the same may beadjusted vertically of the run or channel 6 without interfering with thepulley 9 and sash cord 8.

It will of course be understood that one of the brackets will be seatedin the groove or. channel 6 on each side of a window frame so as tosupport the opposite ends of the shade roller 16. In hanging a shaderoller, one of the brackets is moved to a position slightly below thelevel of the other bracket and the pins or trunnions of said rollerinserted in the openings 15, after which the brackets are moved to aposit-ion in horizontal alinement with each other, and said bracketstogether with the shade roller raised or lowered to the desired positionon the window frame.

It is obvious that in order to remove the roller, it is merely necessaryto drop one of the brackets to a position below the other, when the pinor trunnion of the roller may .be readily detached therefrom so as topermit the shade roller to be taken down.

Particular attention is called to the fact that by making the bracketsin the manner described, both brackets may be lowered to permit thehanging of the shade roller, without the necessity of the operatorstanding on a chair, step ladder or the like to effect the hanging ofsaid roller.

It will also be noted that the sashes may be raised or lowered withoutinterfering with the brackets, and that when thus raised or lowered,said sashes will prevent rain or snow from driving through the windowand wetting or otherwise injuring the curtain.

By making the openings 15 substantially rectangular in shape, the rollermay be readily reversed when necessary, without reversing the brackets,while by forming a plurality of openings in the brackets, the positionof the roller on the brackets may be varied at will according to theconditions under which it is used,

The device is extremely simple in con struction and may be manufacturedand placed on the market at a comparatively small cost.

Having thus described the invention, what is claimed as new is:

1. The combination with a window frame having sash cords and providedwith sash receiving channels, of brackets fitted within the channels infront of the sash cords and provided with means for supporting a shaderoller, each bracket including pivotally united plateshaving their freeends bearing against the adjacent walls of the channels, and springsencircling the pivotal axes of the plates of the brackets and havingtheir opposite ends secured to the free ends of said plates for normallyforcing the latter into engagement with the walls of the channels.

2. A supporting bracket for shade rollers including pivotally unitedmembers 'providecl with depending finger pieces and having their freeends bent to form laterally extending flanges, there being openingsformed in said members for the reception of the trunnions of a shaderoller, and a spring having its intermediate portion encircling thepivotal axis of. said members and its opposite ends secured to the freeends of the members forforcing the flanges into engagement with asupport.

3. A supporting bracket for shade rollers including pivot-ally unitedmembers, each formed from a single strip of flat metal h avingitslongitudinal edges bent to produce angularly disposed flanges, the metalat said flanges being bent laterally to produce serrated lips, therebeing openings formed in said members and perforations arranged nearsome of the openings, the lower end of each member being bent to producea depending finger piece, a disk secured to the pivot pin, and a coilspring having its intermediate portion coiled around the pivot pinbetween the disk and the rear faces of said icmbers and its oppositeends provided with terminal fingers extending through the adjacentperforations.

In testimony whereof, I aliix my signature in presence of two witnesses,
